CPT® Code 26020

Tendons are essential structures in the body, composed of fibrous tissue that connects muscles to bones, allowing for movement. In the hands and fingers, these tendons are encased in protective sheaths that are lined with synovial tissue. This synovial tissue plays a crucial role by secreting synovial fluid, which lubricates the tendons and facilitates smooth movement of the fingers and hands. However, when inflammation or infection occurs within the tendon sheath, it can lead to the accumulation of fluid or pus, necessitating medical intervention. The procedure described by CPT® Code 26020 involves the drainage of the tendon sheath in the digit and/or palm. This is typically performed when there is a need to relieve pressure or remove infectious material that has built up beneath the sheath. The process begins with an incision in the skin over the affected area, followed by careful dissection of the surrounding soft tissues to expose the tendon sheath. A longitudinal incision is then made in the sheath itself, allowing for the drainage of any trapped fluid or purulent material. In some cases, drains may be placed to ensure continued drainage, after which the tendon sheath, soft tissues, and skin are closed around the drains to promote healing.
